Stephen I of Bavaria

Stephen I, Duke of Bavaria (14 March 1271-10 December 1310) was the Duke of Bavaria from 1290 to 1310, succeeding Henry XIII of Bavaria and preceding Henry XIV of Bavaria and Otto IV of Lower Bavaria.

Biography
Stephen was born in Landshut, Duchy of Bavaria, Holy Roman Empire on 14 March 1271, the son of Henry XIII of Bavaria and Elizabeth of Hungary (the daughter of Bela IV of Hungary and Maria Laskarina). He was named after his uncle Stephen V of Hungary, and he was the first member of the House of Wittelsbach to bear the Greek name "Stephen". Pope Nicholas IV refused to allow for Stephen to have a spiritual career in Salzburg, seeking to reduce the influence of the Wittelsbach family, and he instead became co-ruler of Bavaria with his brothers Otto III of Bavaria and Louis III of Bavaria. He was an enemy of the Habsburgs, and he died during a war with Frederick the Fair of Austria in 1310.
